Description

Technical Field

[0001] The utility model relates to the technical field of concrete moulds, in particular to an assembled prefabricated concrete membrane. Background Art

[0002] The so-called formwork in construction refers to the bottom mold of the object's appearance built with materials such as bricks or concrete. It is located outside the ground beam, foundation beam or foundation pit. The brick formwork is made of standard bricks. After it has a certain strength, the concrete pouring work is carried out. At this stage, the concrete formwork is generally built with membrane bricks. The masonry construction requires a lot of manpower costs, and the outside needs to be supported by backfilling. Before backfilling, the inside of the masonry wall needs to be diagonally supported to keep the masonry surface flat and vertical during pouring, which is more troublesome. Utility Model Content

The connecting seam 120 and the connecting seam 220 are used to facilitate the connection between the tensioning assembly 300 and the positioning pin rod 400. The interior of the long side plate 100 is embedded with a steel mesh 160, and the steel mesh 160 is an arc-shaped mesh structure.

[0028] In this embodiment, the strength of the long side plate 100 is improved by the steel mesh 160, and by the setting of the overlapping part 110, when the positioning pin rod 400 is plugged into the two overlapping parts 110, it is convenient for the tensioning assembly 300 to be hooked with the positioning pin rod 400 through the position of the connecting seam 120.
